Specification forming part of Letters Patent No. @1,4123, dated August25, 1868.

To all 'whom 'it may concern:

Be it known that I, AMos SMITH, of Vienna Cross Roads, in the county ofClarke and State of Ohio, have invented a new and useful lmprovement inGrain and Grass Harvesters; and I do hereby declare that the followingis a full, clear, and exact description thereof, which will enable thoseskilled in the art to make and use the same, reference being had to theaccompanying drawings, forming part of this specification.

This invention relates to certain new and useful improvements in grainand grass harvesters.

In the accompanying sheet of drawings, Figure l is a side view of myinvention, taken in the line :v x, Fig. 2; Fig. 2, a plan or top view ofthe same; Fig. 3, a section of the same, taken in the line y y, Fig. l;Fig. 4, a longitudinal section of the pinion and clutch on thepitman-shaft; Fig. 5, a section taken in the line z z, Fig. 2.

Similar letters of reference indicate corresponding parts.

A represents the main frame of the harvester, which is supported by twowheels, B B, each of which has a concentric toothed rim,

C, attached, into which pinions D Dl gear, the

rims G being at their inner sides, as shown clearly in Fig. l. Thepinions D D are placed looseljT on a shaft, E, one pinion, D, having aratchet, a., at one side, which works in a circular recess in the outerside of abevel-wheel, F, which is rmly keyed on the shaft E at ltheouter side of main frame, and engages with a pawl, b, in said recesswhen the Inachine is drawn forward, so as to give motion to the shaft E,said pinion, when the machine is backed,

not rotating the shaft E. This will be fully draft-pole of the machine,which is secured to the front part of the main frame A by a joint orhinge, d, and to the rear end of the draftpole there is attached ametallic socket, G, which is slotted longitudinally, and is fitted andworks O11 a xed perforated guide-plate,

H, attached to the front side of the axle of the machine. By thisarrangement the rear end of the frame A may be depressed at any time bypressing down with the foot on the rear end of the draft-pole. Thedraft-pole may be secured in a iixed position at any time by having apin, c, through the socket G and plate H. I represents the finger-bar,the inner end of which is attached to a shoe, J, the latter beingattached by a joint to a bar, K, the front end of which is bent upward,and has an oblong slot made in it, through which a set-screw, j', passesinto the axle. L is a bar, which is fitted on the crank-boxV g at therear end of the pitman-shaft M. The outer end of the bar L is connectedto the shoe J, and said bar L has a spring-catch, 7L, attached to it,which engages with any of a series of holes made in a pendent bar, N, atthe rear of frame A. (See Fig. 3.) By this arrcngement the nger-bar maybe adjusted higher or lower, as desired, and by means which are entirelyat the outer side ofthe main frame and driving-wheel at the right-handside of the machine.' O represents a hand-lever, which has its fulcrumon the bar K, and has its rear end bearing on a projection on the rearof the shoe J at the inner` side of the joint which connects the shoe tobar L. This' lever O extends through a slot in a guide-plate, l),attached to bar K, and passes upward within convenient reach of thedriver on his seat Q, so that by drawing the lever back the outer endfinger-bar will be raised. R represents the guards or fingers, partbeing secured to the upper surface of the finger-bar I, and the otherpart to the lower which are made of two pieces or parts, jj, onesurface. These parts extend outward in front of the finger-bar as far asthe knives 7c, and no farther. (See Fig.. Il.) The upper parts j oftheguards or'iingers are formed with recesses l, to admit of cones orprojections m on the knives working through, said cones or projectionsserving to clear the cut grass from within the guards or fingers, andprevent the choking or clogging of the same. These cones or projectionsare placed at the roots of the knives, as shown clearly in Fig. 2. Thebevelwheel F gears int-o a bevel-pinion, S, on the pitman-shaft M, thepinion S being connected with shaft M bya clutch, T, as shown in Fig. 4,to admit of said pinion being disconnected from the shaft MWhen it isrequired to render scribed, and the bar K, provided with the the sickleinoperative din-ing a forward movepivot 1l of the lever O, and theslotted standlnent of the machine. ard P, for raising,` the outer end ofthe cutter- I claini as new and desire to secure by Letbar, allconstructed, arranged, and operating; ters Patentsubstantially as setforth.
